The AI bubble may be about to bust.
Peter Thiel has sold all of his Nvidia stock.
We all need to say this very clearly:
NO BAILOUTS FOR THEFT-TECH!
Expropriate their asses instead.
They stole from all of us and fully plan to burn the planet.
They owe us - not the other way around. 1/3

I’m going to regret asking this, but… what mechanism are people proposing whereby AI will “end scarcity”?
This feels like literal underpants gnomes thinking, and as I never tire of pointing out, it’s being driven by a lot of the same actual people

AI could end scarcity, end humanity - or boost trend growth by 0.2 percentage points
